Investigation summary: a large box was received.The box contained a loose 10ml twinpak syringe half-filled with clear medication in a zip lock bag, one used medication vial with some medication in it and labeled ¿tenecteplase,¿ and one empty small packaging kit that listed the above two items in it.Since the samples were contaminated on arrival, they were evaluated visually through the bags only.The syringe was observed to have a hub of the red syringe filling device (sfd) attached.There was no cannula present in the syringe filling device (sfd).It appeared to have been sheared off from the hub as evidenced by deformations at the tip of the hub.The vial had multiple piercing marks where it was punctured by a needle.No cannula was observed in the vial, syringe, nor any bags received.It is possible there was an issue with cannula lubrication or damage to the syringe filling device(sfd), as it is also possible that user error while using the device contributed to the failure.Based on the samples received, it was not possible to determine what may have happened to the syringe filling device's (sfd) cannula.Part of the syringe filling device(sfd) was missing from the samples received which could have provided a missing clue.There were also no unused packaged samples from the same lot received for evaluation of any potential issues.Since root cause could not be determined, corrective actions are not necessary.Furthermore, a device history record review showed no rejected inspections or quality issues during the production of the provided lot number that could have contributed to the reported defect.Complaints received for this device and reported condition will continue to be tracked and trended.Information will be captured on trend reports and monitored monthly.Our business team regularly reviews the collected data for identification of emerging trends.
